Hi

1. what is the horizontal movement being reported in CAESAR II hanger report?
2. is that the movement of the hanger from vertical position?
3. how about the cans, can the spring move in horizontal direction in cans?
4. if yes, what is the limit for that movement? 4 degrees?

thanks

If you assume "Y" is up, this is the movement of the hanger node in the horizontal (X, Z) plane.


This is the movement (displacement) of the hanger node, it is not an angle.


If you don't restrain the pipe in the horizontal plane, yes this movement can occur numerically.


CAESAR II imposes no limits on the solution. This is something you will have to check/verify.

Thanks Richard.

quote 2. the hanger is hanging from something so that displacement means the hanger is at an angle to vertical in OPE case. right?

quote 3. by numerically you mean the can node does not move horizontally in reality?

2) Ok yes, there is an angle. However, the X & Z displacements are just that, the displacements of the hanger node in the horizontal plane.

3) These are the displacements of the pipe node (where the hanger is attached). The "can" itself doesn't move around, but perhaps the pipe can.

Dear Richard :

Please explain a thing to me :

I have placed a pre-defined spring can support "YSPR" in my CAESAR II model.

Should I have to include hanger 'H' in load cases??

Am asking this because when am using load case W+P1 ; the code compliance is 120 %.

but when am using load case W+P1+H ; the code compliance is 84%.

Please help in this regard.

If you don't include the "H", your load distribution isn't correct, because the preload on the YSPR won't be included.
